-# `format_args_capture`
-
-The tracking issue for this feature is: [#67984]
-
-[#67984]: https://github.com/rust-lang/rust/issues/67984
-
-------------------------
-
-Enables `format_args!` (and macros which use `format_args!` in their implementation, such
-as `format!`, `print!` and `panic!`) to capture variables from the surrounding scope.
-This avoids the need to pass named parameters when the binding in question
-already exists in scope.
-
-```rust
-#![feature(format_args_capture)]
-
-let (person, species, name) = ("Charlie Brown", "dog", "Snoopy");
-
-// captures named argument `person`
-print!("Hello {person}");
-
-// captures named arguments `species` and `name`
-format!("The {species}'s name is {name}.");
-```
-
-This also works for formatting parameters such as width and precision:
-
-```rust
-#![feature(format_args_capture)]
-
-let precision = 2;
-let s = format!("{:.precision$}", 1.324223);
-
-assert_eq!(&s, "1.32");
-```
-
-A non-exhaustive list of macros which benefit from this functionality include:
-- `format!`
-- `print!` and `println!`
-- `eprint!` and `eprintln!`
-- `write!` and `writeln!`
-- `panic!`
-- `unreachable!`
-- `unimplemented!`
-- `todo!`
-- `assert!` and similar
-- macros in many thirdparty crates, such as `log`
